Analog electronic timepiece
Abstract:
An analog electronic timepiece includes a stepping motor, a gear train mechanism having gears, a pointer, a drive control unit, a control content changing unit, and a pointer position adjustment unit. If an operational command to rotate the pointer to a different moving target position is obtained while an operational control for rotating the pointer to a certain moving target position is in progress, the control content changing unit terminates the control and changes a control content to an operational control according to the command. If the reverse rotation driving operation is being performed, the pointer position adjustment unit performs an adjustment operation for removing shifting between a predicted position of the pointer and an actual position of the pointer which occurs because of rotational input from the stepping motor not being transmitted to the pointer due to gaps relating to the mesh of the gears.
